To all whom t may concern:

Be it known that I, FREDERICK WILLIAM HUESTIS, a citizen of the UnitedStates, residing at Newtonville,in the county ofMiddlesex and State ofMassachusetts,have invented certain new and useful Improvements inMachines for Making Non-Slipping Treads,Pave ments, etc., of which thefollowing is aspeciication, reference `being had therein to theaccompanying drawings.

Figure l is a side elevation, and Fig. 2 a

front elevation, partly in section, on line 2 2 of Fig. l, of one formot' machine embodying my invention. Fig. 3 is a top plan view of oneform of a sheet-metal base-plate operated upon in my machine. Fig. 4 isa sectional View on line 4t 4. of Fig. 3. Fig. 5 isa perspective Viewshowing a plurality of lead strips of a width and thickness required forcombination with the base-plate, partially combined with the base-plate.Fig. 6 is a sectional view at line 6 6 of Fig. 5 ofa combined base-plateand lead strips, this view illustrating the product of my new machine.Fig. 7 is a side elevation, and Fig. 8 a top plan view, of a modifiedform of machineembodying my invention. Fig. 7a is a front elevation ofthe strip-guide detached.

The object of my invention is to produce a machine for the manufactureof what are commercially known as non slipping treads, pavements, etc.and the machine here shown as an embodiment of my invention is made withparticular reference to the manufactureof treads and the like set forthlin United States Letters Patent N o. 638,666, granted to me as assigneron December 5,1899.

In the drawings illustrating Vthe principle of my invention and thebestmode now known to me of applying that principle, A is the ta-I bleof the machine, and Bis a roll constituting a movable work-support.

D is the pressing and molding roll.

Supporting-roll B is I provided with journals b, mounted in suitableboxes b ot' the machine-frame a, the periphery of the supporting-roll Blying in the recess a of the work-support A and being about liush withthe upper surface of the work-support. Frame a is bifurcated above thework-support A,

means for adjusting the pressing and mold-v ing roll D toward thecooperating movable work-support, which is in the preferred constructionin the form of a supporting roll or Vdrum B, and against the springs d.One of the journals d* of roll D is provided with a gear d3, andthecorresponding journal o of roll B is provided with a gear b2, whichmeshes with gear cl3, so that thetwo rolls are driven together whenpower is applied to the pulley d4 on the other ing and molding roll D.

The machine is provided above table A and on its feed side with arecessed guide-roll F, the journals f of which are mounted inanysuitable bearings f-such, for example,

as the brackets shown fast on the inner legs or bifurcations c2 of theframe c.

The tread, pavement, or the like produced in this machine is made up ofa hard-metal,

preferably steel, plate no, which is provided.

on its upper side with a series of upwardlyprojecting wear-points no.These wear-points oo' are arranged in parallel rows. Between each set ofrows of wear-points to' the plate is formed with rows of perforationsx2, the plate being preferably im perforate, as shown along the lanes orspaces oe3, that alternate with the rows of perforations. The purpose ofthe machine is to combine a plurality of lead strips y simultaneouslywith the plate by pressing` the strips simultaneously through theperfoend of the shaft of the press` rations c2 (so as to anchor the leadon thefrg's back or under side of the plate) and molding the strips andupturned'Wear-points together',

trimming the opposed edges of the lead strips so as to leave the linesor spaces m3, where the plate is imperforate, free and clear of lead.

IOO

The pressing and. moldingiroll D is pro-l `vided with circumferentialand alternating pressing-surfaces D and projecting disks D2. Thepressing and molding surfaces D by pressing the soft-metal or leadstrips y between upturned wear-points of the baseplate on roll B forceportions of the soft strip 'y through the perfor-ations 092 and causethe soft lead to expand and anchor itself at y' on the back of theplate, at the same time forcing the soft metal outwardly between theopposed narrow edges of the projections or wearpoints, as shown at y2 inFig. 5, where end portions of several strips are shown molded intopermanent union with the base-plate. Thus the lead strips aretransformed in shape by pressure and anchored in place on the back ofthe strips and com paeted between the opposed wide surfaces of thewear-points and also compacted between the opposed thin edges of thewear-points, which would remain in that vertical position were it notfor thepreferred molding effect Wrought by the sides of the disks D2 asthey pass between the upturned wear-points along the lines where no leadis to be mounted. The action of the pressing-surfaces D tends to causethe lead to bulge out between the wear-points into vacant spaces orlanes w3, and the disks D2, which are of a greater diameter than thepressing-surfaces D', pass through these lanes w3, the peripheral edgesD3 of the disks D2 forming cutting edges, which cut off theoutwardlybulging or laterally-projecting portions of the soft metal,while the outer marginal and circumferential inclines Dl of the disksD2A v different ways but for cheapness of construction'I prefer to. makethe bearing-surfaces D.l of annuli, each of which has a flat peripheralsurface and a bore of sufficient diameter to iit-the shaft d. The disksD2 are each preferably made of two annuli having an internal boresufficient to iit the shaft dwf. The guide-roll F is similarly made of ashaft f and a series of disks of different diameters f2 f3, mounted onand rotating said shaft.

. These disks lmay have iiat peripheral surfaces, as shown, and they arealternately'disposed on the shaft, so that the larger or projectingdisks f3 travel in the lanes or vacant spaces ac3 of the base-plate, theedges of each lead strip being laterally guided by the projecting sideedges of the disks f3 and controlled across their tops by theiiatperipheries iof the smaller disks f2 between the larger Gespecprojecting disksfs. The disks f2 and f3 forni alternating indentationsand projections.

The base-plate being mounted on table A in such position that the largerdisks f3 will run along the vacant lanes of the base-plate and the freeends of the desired number of lead strips being mounted between thelateral edges of the disks f3 and in line with the rows of perforationsx2 between the upturned wear-points w rotation of the cooperating rollsB and D aft-er the adjacent ends of the base-plate andtherewith-assembled strips have been pushed between the rolls, so thatthey nip the work, feeds the work forward, and the strip and plate aremolded together. The cutting edges D3 of disks D2 are each mounted in avertical plane corresponding with that of one of the larger disks f3 onthe guide-roll F, and each pressing-surface D is mounted in the plane ofthe smaller disk f2 on the guide-roll F. By means of this machinefaplurality of lead strips are simultaneously molded and combined with ahardmetal base-plate, and the pavement or tread already patented by mysaid patent is very speedily and economically manufactured. By theaction of this machine the lead strips are each transformed by pressureinto an anchored non-slipping filling, and the sheet' metal plate inrespect of the upturned wears points is also transformed by pressureinto a plate having a plurality of wear-points, the upper surfaces ofwhich are flush with the anchored lead and also curved slightlyinwardly, so as to form projecting surfaces for the upper outwardcorners of the anchored f lead and to form upwardly and outwardlyflaring grooves or lanes on the surface of the finished tread, wherebythe escape and displacement of dirt are more readily effected than wouldbe the case were the upturned wear-pointsleft vertical. y The apparatusherein set forth may be used in practicing the method set forth in myal= lowed application, Serial No. 10,461, of even date herewith.A InFigs. 7, 7, and 8, showing a modification, the work-support A is thereciprocating -bed of an ordinary planer and constitutes the movablework-support of this form of machine. Y The guide instead of being aninter mittently-recessed roll, as in the preferred form, is a stationarytransverse bar e", having a series of recesses z" along its lower edge,these recesses being adapted to receive the lead strips. The pressingand molding roll z2 is mounted in'a bracket z3, fast to the Verticaluprights a4. It is not intended that roll z2 be driven by belt orgearings on its journals, for the roll will rotate when the combinedtread-plate and lead strips are carried j underneath it by thereciprocation of the bed A. I have therefore used this modifiedconstruction with good results and illustrate it here for the purpose ofshowing that the horizontal reciprocating bed of the planer is themechanical equivalent of the work-support and supporting-roll of thepreferred form n of my machine. In Fig. 8 I show a plate a:

. clamped in place on the bed of the machine.

having recessed strip-pressing surfaces which alternate with projectingdisks; a projecting disk bearing at each side of a strip-pressingsurface, and having two cutting peripheral edges, one at each side ofthe projecting disk; aguide-roll located above said table and providedwith collars, the recesses formed there# by being in alinement with therecesses in the presser-roll; means for elastically mount# ing andadjusting the presser-roll relatively to the supporting-roll; and meansfor operatively connecting said presser-roll and said supporting-roll.

In testimony whereof I affix my signature in presence of two witnesses.
